leonsenft 34817da735 refactor(core): defer foreign component rendering to post-update pass

Foreign components imported via foreignImports and created by the
ɵɵforeignComponent instruction were previously rendered eagerly in the
creation phase (rf & 1) of the template. This restricted which
properties could be passed to foreign component props, as parent-bound
inputs (@Input(), input(), input.required()), properties initialized in
ngOnInit(), and pull-based view queries (viewChild()) were not yet
initialized at creation time.

This change defers foreign component rendering to run as a view effect
during the update pass:
- Update ɵɵforeignComponent in core to schedule component rendering via
  createViewEffect (executed in runEffectsInView during refreshView),
  executed with setActiveConsumer(null) to prevent reactive context
  leakage and destroyed immediately upon first execution.
- Update ɵɵforeignComponent to strictly accept props as a factory function
  (() => props) or null.
- Update the compiler template pipeline to wrap foreign component props
  in an arrow function closure (() => ({ ... })).
- Hoist creation-time foreign content projection instructions
  (ɵɵforeignContent, ɵɵforeignContentFn) into creation-phase variable
  declarations before ɵɵforeignComponent so creation-time context is
  captured safely.
